Two watches, one drawer — at least one of them is always wrong.
The Onyx keeps both automatics wound and ready side by side, in a sleek black wood case built to disappear into any room.
- Black wood finish: sober and modern, reads as luxury without the gloss
- Two independent winding slots: each watch on its own direction and speed
- Silent motor per slot: two watches running in a bedroom without a sound
-
CW / CCW / Alternating: covers every automatic movement
- Compact footprint: bedside-table-friendly — no space demands on your room
For the two-watch collector who wants a quieter, darker winder instead of a glossy display piece.

Frequently Asked Questions
An automatic watch relies on the motion of your wrist to stay wound. When you're not wearing it, a watch winder mimics that movement — rotating continuously at calibrated intervals to keep the mainspring tensioned. The result: your watch is always accurate, always ready to wear. No more resetting the time, date, or moon phase every time you pick it up.
Every Gentleman Winder is delivered to any UK address within 4 to 8 working days, fully tracked at no extra cost. You'll receive a dispatch email with your tracking link as soon as your order leaves our warehouse.
Every Gentleman Winder comes with a 30-day satisfaction guarantee. If you're not completely happy — for any reason — contact us within 30 days of delivery and we'll arrange a full refund, no questions asked.
No — provided it's set correctly. Every Gentleman Winder is calibrated to rotate within the safe TPD (turns per day) range recommended by watch manufacturers. Over-winding is not possible with an automatic movement, as the mainspring disengages once fully tensioned.
Gentleman Winder works with all automatic (self-winding) movements, regardless of brand or size. It is not compatible with quartz or manual-wind watches. If you're unsure whether your watch qualifies, feel free to contact us — we're happy to advise.
